7. Weaving of Cloth is being done in looms. It was seen that defects like coagulation of thread, Knot, Breakage in continuity of thread, Grease marks are opportunities of defects. The number of such defects were found to be 20 in the 100 dhotis woven. Calculate the six sigma level at which the looms was operating. Ans: No. of Defects = 20 Total No. of Dhotis Woven = 100 No. of Opportunities = 4 (coagulation of threads, knot, breakage of continuity of threads & grease marks) Defects per unit (DPU) = D/U = 20/100 = 0.20 Defects per opportunities (DPO) = 20/ (4*100) = 0.05 Defects per million opportunities (DPMO) = 0.05*106 = 50000 PPM Z = 0.5 – 0.05 = 0.45 Z Value = 1.645 Sigma Value to Z = 1.645 + 1.5 = 3.145 8.
